I think a lot of moms start with the online stuff but should do the craft fair or farmers market route instead.
I now also have an Etsy shop ,but it is not how I make most of my money.
Nothing beats to one on one interaction of real customers. You can see what they are interested in, see the reaction to your prices,and they ask questions that can help you direct your marketing on line as well as in your booth.
It is much harder to make money online so I use it as a supplement and for my local customers to refer friends that are not local.
Hope that helps.
